IPC: B41J2/165
Filed: 1999-11-24
Abstract: PURPOSE: An ink cartridge is provided which enables pieces of information relating to the ink cartridge, for example, information on a remaining quantity of each ink, to be stored efficiently in a storage element, while reducing the manufacturing cost of the ink cartridge including the storage element. CONSTITUTION: An ink cartridge (107K, 107F) has a storage element (80K, 80F), in which plural pieces of specific information relating to the ink cartridge (107K, 107F) are stored at specific addresses that respectively occupy minimum bits required for storage. Namely the storage capacities required for storing the respective pieces of specific information are different from one another. For example, a piece of information on the year of manufacture is registered in a data length of 7 bits, a piece of information on the month of manufacture is registered in a data length of 4 bits, and a piece of information on the date of manufacture is registered in a data length of 5 bits. A piece of information on the time (hour) of manufacture is registered in a data length of 5 bits, and a piece of information on the time (minute) of manufacture is registered in a data length of 6 bits. A piece of information on the validity term of ink is registered in a data length of 6 bits, and a piece of information on the after-unsealed validity term is registered in a data length of 5 bits. This arrangement enables the specific information relating to the ink cartridge (107K, 107F), for example, pieces of information on the manufacture of the ink cartridge (107K, 107F), and those on remaining quantities of the respective inks, to be stored efficiently into the storage element (80K, 80F), while reducing the manufacturing cost of the ink cartridge (107K, 107F).

Abstract: PURPOSE: A deciding method for existence of an optical disk is provided to decide existence of the optical disk regardless of noise by using a focusing OK signal detected by an RF(Radio Frequency) signal read from the optical disk. CONSTITUTION: After initializing an added value, an optical pickup is transferred toward a disk. A signal from the optical pickup is compared with a reference level for outputting a focusing OK signal. Then, a focusing error signal is sampled by controlling an A-D(Analog-Digital) converter. Then, sampled values over a low reference level are added. In case of the added value over an established value, existence of an optical disk is decided. Otherwise, absence of the optical disk is decided. Herein, noise higher than the low reference level is decided as being included in the focusing error signal.
